The jemalloc memory allocator "malloc" implementation has been popular for HPC and server use down to desktop use in apps like Firefox. Jemalloc has proven over the years to be effective on delivering better performance and scalability while enjoying lower memory usage and less fragmentation than alternative malloc implementations. Meta recently announced that they are renewing their investment into jemalloc...

An interesting Linux detail from today's NVIDIA GTC 2026 kickoff is that Canonical will be integrating NVIDIA's DOCA-OFED software framework into the Ubuntu Linux archive for leveraging the high-speed networking stack for HPC and AI...

A bit of time has passed since having any exciting performance improvements to report on within the GNU C Library "glibc" but that changed today with another nice x86_64 optimization for modern CPUs...

FFmpeg 8.1 is out today as the newest stable release of this widely-used, open-source multimedia library...

The Linux kernel's extensible scheduler class "sched_ext" to allow for custom CPU scheduling policies as BPF programs continues enabling new functionality. Queued up in the sched_ext development code ahead of next month's Linux 7.1 cycle is the new SCX_ENQ_IMMED capability for enabling tighter control over when tasks land on a CPU...

Since last week's Fedora 44 Beta release I have been testing out this upcoming Fedora Linux version on a few systems in the lab, most notably with the Framework Desktop powered by the powerful AMD Ryzen AI Max+ 395 "Strix Halo". Fedora Workstation 44 Beta has been looking nice and running stable albeit in some instances seeing lower performance at this point than Fedora Workstation 43 but overall in good shape.

The past several years Imagination Tech has been investing in an upstream and open-source DRM kernel graphics driver as well as a PowerVR Vulkan driver in Mesa. Their Mesa focus has exclusively been on the PowerVR Vulkan driver with the plans all along to use the Zink generic OpenGL-on-Vulkan implementation. With next quarter's Mesa 26.1 release, that goal is being realized with Zink now working nicely atop the PowerVR Vulkan driver for in turn achieving open-source OpenGL support on PowerVR...

A round of Intel graphics driver updates were sent today to DRM-Next in staging ahead of April's Linux 7.1 merge window. The changes in this pull aren't too particularly exciting with a lot of code refactoring and other work, but there are preparations made for supporting UHBR DP tunnels...

The work by Derek Clark on enhancing the Lenovo Legion Go gaming handheld support for Linux continues panning out nicely. The latest driver effort, the creation of the Lenovo Legion Go and Go S Series HID Drivers to help with controller configuration, is set to be introduced in Linux 7.1...

The upcoming Linux 7.1 kernel cycle is set to retire UDP-Lite support. The UDP-Lite protocol allowed for partial checksums where potentially damaged/corrupted packets are still delivered to the application. Since the Linux 2.6.20 days there has been UDP-Lite support but the kernel is now set to retire it given breakage that has persisted for years and cleaning up the networking code can yield a performance advantage for non-UDP-Lite users...

A four year old optimization idea for the RADV driver was scratched off the TODO list last week for next quarter's Mesa 26.1 release...

Last week yet more AMDGPU kernel graphics driver updates were submitted to DRM-Next ahead of the Linux 7.1 merge window happening in April...

We are down to about one month to go until the Linux 7.0 stable release and out today is Linux 7.0-rc4...

Kent Overstreet today released Bcachefs 1.37 as the newest feature release to this out-of-tree file-system driver and user-space tooling for this next-gen, copy-on-write file-system...

Merged to mainline yesterday for Linux 7.0 were yet more Rust changes in preparing for upcoming Rust releases as well as enhancing the kernel build reproducibility when engaging the Rust code...

This week's "sched/urgent" pull request was sent out today of scheduler updates for the ongoing Linux 7.0 cycle. Notable this week are fixing some hangs as well as a possible performance regression on large systems...

In addition to GNOME OS seeing recent improvements, KDE Linux continues seeing more enhancements too for this leading reference platform for showcasing the KDE Plasma desktop...

SuperTux 0.7 officially released overnight for this nostalgic open-source game now seeing its first new release since December 2021. SuperTux 0.7 brings many significant improvements for this open-source game inspired by Super Mario...

An open-source, independently developed Linux kernel module called GreenBoost aims to augment the dedicated video memory on NVIDIA discrete GPUs with system memory and NVMe storage. The intent here with GreenBoost is a CUDA caching layer to more easily run larger AI models for LLMs that otherwise won't fit solely in your graphics card's dedicated vRAM...

Just under one year since the long-awaited GIMP 3.0 release, GIMP 3.2 is out today as the first feature release building off the GIMP 3.0 foundation...
